I NVENTOR United States Patent 3,272,102 PHOTO-TYPESETTING MACHINES Nobuo Morisawa, 351 Hitomaru-cho, Akashi, Japan Filed Aug. 5, 1963, Ser. No. 300,018 2 Claims. (Cl. 95-4.5)

This invention relates to a photo-typesetting machine, and its object is to improve the efiiciency of the machine and at the same time lessen the oper-ators fatigue.

Known types of photo-typesetting machines, which are worked mainly by hand, are low in efficiency and cost the operators comparatively much labor and fatigue.

With this object in view the present invention provides a photo-typesetting machine wherein a letter board is moved to place a necessary letter thereon under a tube provided with a lens therein and fixed there by pressing a button, then by pushing another button the shutter in the tube is electrically operated to photograph the letter, and after that the magazine is electrically moved sideways by a length proportionate to the breadth of the letter, electrically regulated.

According to the present invention, not only will phototypesetting machines improve in efiiciency but the operators can be saved much labor, as compared with known types.

Other and further objects of the present invention will become apparent from the following specification and claims taken together with the accompanying drawings in which is shown the preferred embodiment of the phototypesetting machine according to the present invention.

In these drawings reference numeral 21 indicates a letter board which is a black plate with a plurality of transparent letters set therein in a prescribed order, and is attached to an upper movable plate 22. In order to make it easier to see these letters on the letter board 21, which are in reverse form, an indicator board. 23 is attached .to the upper movable plate 22 in front of the letter board 21, letters on the indicator board 23 corresponding in position to those on the letter board 21. To the upper movable plate 22 is fixed a rack 24 behind the letter board 21, and behind the rack 24 are positioned adjusting pieces 25 proportionate in height to the breadths of the letters on the letter board 21, their positions corresponding to those of the letters. For the adjusting pieces 25 it is preferred to use rods which are circular in section. The upper movable plate 22 is so attached as to be moved sideways on a lower movable plate 26, which in its turn is so attached to a base plate 27 of a frame 28 that it can move transversely a distance corresponding to the distance between two of the lines of letters on the letter board 21.

To the frame 28 is attached one end of a lever 29, the free end of which is provided with a pawl 30.

On a support 31 fixed to the frame 28 is mounted another lever so as to pivot about a point at the middle thereof, and the middle of the lever 29 and one end of the lever 32 is connected by a rod 33, around which is wound a spring 34. The frame 28 is provided with an electromagnet 35, having the lower end of the movable iron core 36 thereof linked with the other end of the lever 32. When a button 37 on the base plate 27 is pressed, a switch S (FIG. 8) is worked, and the electromagnet 35 is excited and attracts the movable iron core 36, so that through the work of the levers 32 and 29 the pawl 30 engages with the rack 24, and the letter board 21 is fixed while a letter is photographed.

In a box 38 (FIG. 1) at the bottom of the frame 28 is furnished a light source such as an electric lamp 3 9, on one side of which is mounted a reflector 40 and on the other side a reflecting mirror 41. "To the frame 28 is fixed a tube 42 having a lens therein. In the frame 28 is fixed a support 43 (FIGS. 1 and 2) holding an electromagnet 44, the movable iron core 45 of which is connected by levers 46 and 47 (FIG. 3) to a shutter 48 provided on the tube 42. When a button 49 (FIG. 1) on the base plate 27 is pressed, the electromagnet 44 is excited and attracts the movable iron core 45, as will be explained later, so that the levers 46 and 47 turn and open the shutter 48, and when the button 49 is released the shutter 48 closes. Thus one of the letters on the letter board 21, lit by the light source 39, is photographed on sensitive paper in a magazine the moment the shutter 48 is opened.

In the box 38 is furnished an electric motor M (FIG. 8), the shaft of which is connected to a cam shaft 50 by a clutch, -as described later, and on this cam shaft 50 are fixed a pair of cams 51 and 52, and an eccentric disc 53. The box 38 has a pin 54 fixed therein (FIG. 1, FIG. 4), to which is attached the middle of a lever 55, one arm being provided with a roller 56 for a follower for the cam 51, and the other arm being linked with a movable rod 57, which is connected to a movable rod 58 by a piece 59, slidably engaged therewith (FIG. 3, FIG. 4). Between the piece 59 and a stop 60 fixed at the upper end of the movable rod 57 is mounted a spring 60 The lower end of the movable rod 58 is right above one of the adjusting pieces 25, and the upper end thereof is connected to another movable rod 58 On a rotatable rod 61 furnished in the frame 28 are mounted a link 62, 63, the link 62 being coupled with the movable rod 58 and the link 63 being coupled with another link 64. On the front end of a shaft 65 are mounted a ratchet wheel 66 fixed on the shaft and a lever 67 loosely mounted on the shaft, on the outer end of lever is fixed an arc-shaped cover 68, kept lightly in contact with a part of the periphery of the ratchet wheel 66. The lever 67 has the link 64 joined thereto at the middle thereof.

When the cam 51 rotates, the lever 55 turns, so that the movable rod 57 goes up and down vertically, and together with it the movable rods 58 and 5-8 carry out a vertical reciprocation, each time being brought down into contact with one of the adjusting pieces 25. At the same time, through the link motion of the links 62, 6-3 and 64, the cover 68 turns a distance proportionate to the height of the adjusting piece 25, and thus regulates the rotation of the ratchet wheel 66, as described later in detail.

To the eccentric disc 53 fixed on the cam shaft 50 is attached an eccentric rod 69, the upper part of which is joined to a link 70 mounted on a rotatable rod 70 mounted on the frame 28 and a link 76 mounted on the rod 70 is connected to an arc-shaped lever 71 by a link 72. The lever 71 is provided with a pawl 73 on an arm which extends in the radial direction of the ratchet wheel '66. On a frame 28 is attached a check pawl 74, and the movement thereof is controlled by a stopper 75 fixed on the pawl 73. When the eccentric disc 53 rotates, the eccentric rod 69 carries out a vertical reciprocation, and through the link motion of the links 70, 76 and 72 the arc-shaped lever 71 turns, so that the pawl 73 turns in contact with the surface of the cover 68, and the pawl 73 engages with the ratchet wheel 66 the moment it outruns the cover 68 and turns the ratchet wheel 66. Therefore the peripheral distance the ratchet wheel 66 goes is decided by the peripheral distance the cover 68 goes. Thus through the rotation of the ratchet wheel 66 and through the gearing, which is explained later, a magazine 77 provided with sensitive paper therein is moved sideways a length proportionate to the breadth of the letter chosen among those on the letter board 21.

In FIG. 8 letter M indicates an electric motor, numeral 78 a transformer, numerals 3 5 and 44 electromagnets, numeral 79 an electromagnetic clutch, numeral 50 a camshaft, numeral 51 a cam, numeral 52 a cam for a switch S numeral 80 a relay, and letter S a switch for a relay 80.

When the button 37 is pressed, the switch S closes, the circuit of the electromagnet 35 is closed and as aforesaid, the letter board 21 is fixed, and when the button 37 is released, the circuit of the eleotromagnet 35 is opened. Then when the butt-on 49 is pressed, the switch S5 closes and excites the electromagnet 44, the shutter 45 opens, the letter is photographed, and at the same time the electromagnetic clutch 79 works, driving the motor M and together with it the camshaft 50. When the button 49 is released, the switch S opens the circuit, but the circuit of the electrornagnet 4 4 being still closed by the switch S the camshaft 50 goes on revolving, and each time the cam 52 makes one rotation, the circuit of the electromagnet 44 is opened by the switch 8 by the agency of the cam 52, so that the electromagnetic clutch 79 is taken off the electric motor M and the camshaft 50 stops revolving. Thus during a turn of the camshaft 50 the cover 68 is moved through the work of the cam 51 and regulates the work of the pawl 73 turning the ratchet wheel 66, as above explained, and the magazine 77 is moved sideways a distance proportionate to the breadth of the letter chosen among those on the letter board 21, through the gearing explained hereafter.

In order to photograph those letters on the letter board 21 in various enlarged sizes, the lens in the tube 42 must be changed, and for this it is necessary to vary the distance the magazine 77 is moved sideways. As shown in FIG. 6, on the shaft 65 of the ratchet wheel 66 is fixed a gear 81, meshed with a gear 82, and on the shaft 83 thereof are fixed a plurality of gears 84 of different pitches, arranged in order of pitch. To the rod 85 fixed to the frame 2 8 are rotatably attached handles 86 at the positions corresponding to those of the gears 84, each of the arms 87 of which is provided with an intermediate gear 88 (FIGS. 7, 10, 11). On a shaft 89 fixed in the frame 28 is fixed a gear 90 elongated in the .axial direction, and to the shaft 89 is fixed another gear 91, meshing with a pinion 92 which is meshed with a rack 93 fixed on a magazine holder 94 slidably mounted on the frame 2 8. When the ratchet wheel 66 is turned, the magazine holder 94 is moved sideways through the gearing of the gears 81 and 82, the gear 84 and the intermediate gear 88 and the gear 90, the gear 91 and the pinion 92, and the pinion 92 and the rack 93. The selected intermediate gear 8 8 meshes with corresponding .one of the gears 84 and Ill? gear 90, while the other intermediate gears 88 are kept free. Each of the handles 86 is provided with a spring 95, and while they are kept in upper recesses 96 of the slits 97 vertically cut in the side plate of the frame 28, the intermediate gears 88 are kept in their regular disengaged positions. When the selected handle 86 is moved into a lower recess 98 of the slit 96, the intermediate gear 88 of that handle '86 meshes with the corersponding gear 84 and the gear 90.

In order to send sensitive paper lengthwise in the magazine 77, that is, send it to the position for photographing the next line after one line is finished, the present invention provides the following device worked by hand. As shown in FIGS. 12, 13 and 14, a winding drum 9-9 for sensitive paper rotatably mounted in the magazine 77 has a gear 100 also acting as a clutch fixed on one end thereof and meshed with a gear 101, which is fixed on an axially movable shaft 102, so as to be taken off it, if necessary. On a shaft 103, on which a gear 104 is fixed and meshed with the gear 102, is fixed :a gear 105 placed in a gearbox 106. Also in the gearbox is a gear 107 meshed with the gear 105 and mounted on a shaft 108, to which is fixed a ratchet wheel 109 and a loosely attached lever 110 provided with a pawl 111. In the gear box 106 is fixed a cylinder 112 having thereon a circular groove, in which is loosely positioned a ring 113, and to this ring is attached a lever 114 provided with an arc-shaped cover 115 kept in contact with the peripheral surface of the ratchet wheel 109. Further the gear box 106 is provided with a check pawl 116, the other part of which protrudes through the gear box 106.

When the cover 115 is moved round the ratchet wheel 109 a proper distance by the lever 114 and the pawl 111 is move-d up the surface thereof by the lever 110, the pawl 11 1 engages with the ratchet wheel 109 the moment it gets off the cover 115, and the winding drum 99 is turned by the gearing of the gears 107 and 105, and the gears 103, 102 and 100, sen-ding the sensitive paper to have the next line photographed. When the pawl 116 is removed from the ratchet wheel 109 by pressing the outer end thereof, the winding drum 99 can be freely turned.

When a necessary letter is placed right under the tube 42 by moving the letter board 21 and the button 37 is pressed, the electromagnet 35 is excited, and the pawl 30 meshes with the rack 24, fixing the letter board fast. Then when the button 49 is pressed, the electromagnet 44 is excited, the shutter 48 opens, and the picture of the letter is taken on sensitive paper in the magazine 77. When the button 49 is released, the electromagnet 44 loses its magnetism and the shutter 48 is closed, but the moment the button 49 is pressed, the relay 80 works, so that the electromagnetic clutch 79 works and the camshaft 50 is revolved together with the electric motor M, and when the camshaft 50 finishes a revolution, the switch S opens the circuit and the camshaft 50 stops rotating. While the camshaft 50 makes one rotation, the cover 6 8 goes around a distance proportionate to the breadth of the letter through the work of the cam 51, and by the work of the eccentric disc 53 the pawl 73 turns the ratchet wheel 66, engaging with it when it overruns the cover 6 8, so that the magazine 77 is moved sideways a distance proportionate to the breadth of the letter. Thus each time the buttons 37 and 49 are pressed, one of the letters on the letter board 21 is photographed, and when a lineris finished the winding drum 77 is turned lengthwise by hand. In order to set the letters in a larger type, it is necessary to change the lens in the tube for a suitable one and move another lever 86 into the lower recess 98 of the slit 97, so that the magazine 77 can be sent sideways by just enough distance for the new type. In this way letters on the letter board 21 can be set in various enlarged sizes.

It is thought that the invention and its advantages will be understood from the foregoing description and it is apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing its material advantages, the form hereinbefore described and illustrated in the drawings being merely a preferred embodiment thereof.
